Temporomandibular Disorder (TMD) is a clinical syndrome that mainly affects the masticatory muscles and temporomandibular joints (TMJ). The manual palpation is the most used clinical method to evaluate the muscle pain and is considered an important part of the clinical examination. The pressure algometry is used to verify the initial threshold of myofascial pain perception in the temporomandibular disorder. The purpose of this research was to evaluate the pain threshold change in patients with muscle-type TMD before and after the conservative treatment. Twenty seven volunteers were screened according to the Research Diagnostic Criteria (RDC/TMD), and 14 had muscle TMD and 13 with absence of TMD (control group). Measurements were taken with the pressure algometer in every patient in temporal and masseter muscles in order to quantify the response to the patient painful stimulus. After the proposed treatment the patient was scheduled to return in 7,14, 28 and 56 days. Therefore, it resulted in 18 patients for the study. The algometer comparison between the groups treated before and after the care, showed an initial value (in KgF) of 0.827 ± 0.405 and final of 1.416 ± 0.745, p<0.001 (significant level of 5%). With this research, it can be concluded that patients with muscle-type TMD treated conservatively tolerate a greater load of pressure after the treatment.
